Multidetector Computed Tomography Perfusion in Head and Neck Squamous Cell Carcinomas: Evaluation of a Dose Reduction Strategy.

 Computed tomography perfusion (CTp), a useful technique in oncology, is not widely utilized due to the high radiation dose delivered from it. It involves scanning the region of interest every second for 50 seconds following intravenous contrast administration. Doubling sampling interval (SI) to 2 seconds will half the radiation dose, but may impact its effectiveness, which needs to be evaluated.

Intersectional Antiracist Advocacy Practice in Health Care Organizations.

Health care organizations, like individuals, can evolve to become antiracist and promote racial equity within and beyond the organization. In this brief article, we introduce an intersectional antiracist advocacy practice framework applicable to health care organizations that seek restorative and transformative change, as well as participation in social and economic justice action. Becoming an antiracist organization requires an acknowledgment that no organization is impervious to racist and other oppressive ideologies.

Postprandial endothelial dysfunction and CIMT after oral fat challenge in patients with type 2 diabetes mellitus with and without macrovascular disease - A preliminary study.

Background: Very few studies have reported on association of postprandial lipids and endothelial dysfunction among patients with diabetes. Whether endothelial dysfunction particularly postprandial FMD is worse in patients with T2DM with macrovascular disease compared to those without and whether this difference is related to postprandial hypertriglyceridemia (PPHTg) is unclear. Therefore, present study was aimed to assess the relationship between PPHTg and endothelial function in patients with T2DM with and without macrovascular disease.

Centering a pedagogy of care in the pandemic.

This essay is a reflexive account of my experience of teaching a social justice course during the pandemic. Specifically, I reflect on how centering a pedagogy of care within the course provided a framework for me to be responsive to student needs while also disrupting dominant culture and neoliberal forces in academia. In particular, I highlight sharing power and co-creating meaning, community care, and use of creativity and mindfulness as disruptions to dominant paradigms that I employed in my class that were impactful in the context of the pandemic.

Pandemic and protest in 2020: Questions and considerations for social work research.

The convergence of the COVID-19 pandemic and social/political protest concerning structural anti-Black racism marks a moment for deep reflection and revision of many taken-for-granted assumptions about our research and academic lives as social work scholars. In this reflexive essay we, as two non-Black qualitative social work scholars, explore some of the questions and considerations for social work research that have surfaced since the emergence of these complex social, political, and economic crises. We organize our reflection around we study, and we go about studying it.

Mandating Inclusion: Critical Trans Perspectives on Domestic and Sexual Violence Advocacy.

In 2013, the Violence Against Women Act became one of the first federal laws to explicitly prohibit discrimination against transgender people, yet little is known about its impact in practice. This qualitative study draws on in-depth interviews with transgender people working in domestic and sexual violence advocacy organizations. Building on critical and intersectional perspectives, the findings suggest that the persistence of inequities for trans survivors are tied to the reliance on criminal legal responses, contingent access to gender-specific services, compliance-focused approaches to inclusion, operating theories of gender-based violence, and the diversion of responsibility to LGBTQ (lesbian, gay, bisexual, transgender and queer) programs.

Studies on the time course of apparent diffusion coefficient and signal intensities on T2- and diffusion-weighted MR Imaging in acute cerebral ischemic stroke.

The time course of changes in apparent diffusion coefficient (ADC) and signal intensity on diffusion-weighted magnetic resonance imaging (DW MR) imaging in acute ischemic stroke is a very dynamic event. There is an initial reduction in ADCs with no change on T2-W imaging but signal intensity increase on T2-weighted takes place about 6-12 hours after onset of stroke. As necrosis begins to set in, there is a gradual reversal of ADC change, and around 3-10 days post-onset, ADC pseudonormalizes.
